Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Part A
ASN-002 and 5-fluorouracil (5-FU) to be administered as separate intratumoral injections into the same target lesion on the same day.
Arm 1: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] in addition to 5mg chemotherapeutic agent weekly for 3 weeks [cumulative dose 15mg]
Arm 2: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] in addition to 15mg chemotherapeutic agent weekly for 3 weeks [cumulative dose 45mg]
Arm 3: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] in addition to 25mg chemotherapeutic agent weekly for 3 weeks [cumulative dose 75mg]

Part B
ASN-002 to be injected intratumorally into the same target lesion on 3 occasions.
Arm 1: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] split between 2 or 3 lesions
Arm 2: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] split between 4 lesions
Arm 3: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] split between 5 lesions
Arm 4: 1.5 X 10(11) ASN-002 viral particles per week for 3 weeks [cumulative dose 4.5 x 10(11)] injected into a single lesion

Participants will only be recruited into one of the study arms. Participants with a single lesion will be recruited into either Part A; Arm 1, 2 or 3 or Arm 4 of Part B. Participants with 2 or more lesions will be recruited into Part B; Arms 1, 2 or 3. For participants in Part B Arms 1, 2 and 3, doses of ASN-002 are split evenly between lesions.
Fidelity of the treatment schedule will be directly via the Principle Investigator who will inject all lesions.

Outcomes
Primary outcome [1] 321057 0
Safety and Tolerability of ASN-002 injected in combination with chemotherapeutic agent as assessed by examination of changes in vital signs, adverse events, serious adverse events, laboratory abnormalities and withdrawals from study as well as local skin and injection site responses and inflammation.
Timepoint [1] 321057 0
Weeks 2, 3, 4, 17 and 24 post first dose. Phone call follow up on day 2 and 3 post each ASN-002 injection.
Primary outcome [2] 321058 0
Safety and Tolerability of ASN-002 injected into 2-5 previously untreated BCCs as assessed by examination of changes in vital signs, adverse events, serious adverse events, laboratory abnormalities and withdrawals from study as well as local skin and injection site responses and inflammation.
Timepoint [2] 321058 0
Weeks 2, 3, 4, 17 and 24 post first dose. Phone call follow up on day 2 and 3 post each ASN-002 injection.
Secondary outcome [1] 373831 0
Evaluate the histological clearance of injected BCCs by histopathology.
Timepoint [1] 373831 0
Tumours are resected 24 weeks after commencement of intervention. Tumours are assessed by microscopic examination and compared histopathogically to biopsies collected prior to commencement of therapy.

Intervention assignment
Parallel
Other design features
The Investigator may enrol eligible participants into either Part A or B. In Part A, three combination Arms will receive a low (5mg), intermediate (15mg) and high dose (25mg) of chemotherapeutic agent per injection weekly for 3 weeks, i.e. total cumulative dose of 15 mg, 45 mg and 75 mg respectively. The high dose Arm will only be enrolled if the low and intermediate doses show acceptable safety and tolerability. The high dose Arm will be enrolled at the discretion of the Investigator.
Eligible participants will be enrolled sequentially in the low and intermediate dose Arms or as decided by the Investigator based on clinical presentation.
Phase
Phase 2
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
This is an early phase study. The number of participants to be treated in each arm has been determined arbitrarily by the Investigator and Sponsor based on results in previous studies.
All data will be provided in data listings sorted by Study Arm and participant number. Categorical data, including clinical and histological responses for injected and any non-injected lesions, will be summarised by the number and percent of participants falling in each category. Continuous variables will be summarised by descriptive statistics including mean, standard deviation, median, minimum, and maximum.
